How to Choose a Goldfish Tank?

There’s a lot more to choosing a best goldfish tank than meets the eye. Here are some things to consider when choosing one.

Goldfish Tank Size

As we said, goldfish can live for a long time. In order for them to reach their full maturity potential, the right tank is essential.

Since goldfish grow very quickly, it is best to start with a larger tank so you don’t have to keep updating.

What’s an ideal size?

Opt for 20 gallons for one or two goldfish. There are a few reasons to have a tank of this size.

Large aquariums are easier to keep clear, especially if you only have one or two fish in them. That means less maintenance, fewer water changes, and a happier, calmer goldfish.


Goldfish are very sensitive to temperature which is why water changes can be so stressful. Not only that, but the larger the tank, the less sensitive the water is to changes in ambient temperature.

Here’s the thing, goldfish are meant to be pretty big. If their surroundings were unobstructed, they could grow to more than 25 cm in length. Keeping them in a small container that inhibits their growth prevents their body from developing properly.

Goldfish can also live for a long time. If their growth is stunted, they usually only live a few years. Believe it or not, goldfish can live up to 20 years in the right conditions.

Goldfish grow very quickly and can be very heavy. As a result, they consume a lot of oxygen, so a large tank with a lot of surface is essential for their well-being.

Another reason having a large tank is a good idea is because goldfish are pretty messy. They are large and generate a lot of waste. Having more water dilutes the waste, affecting the quality of the water much more slowly than in a small tank.

Another thing to consider is whether you want more than one goldfish. They are a social species and enjoy company. That said, more fish means a bigger tank. You need to add 10 gallons of water to the tank size for each additional fish.

As for the shape, keep in mind that more surface area is better. Rectangular tanks are the best shape for this. Also, your goldfish will love to swim the length of the tank instead of swimming up and down. Avoid tanks that are too deep or oddly shaped.

Acrylic vs Glass

There are advantages and disadvantages to both glass and acrylic so the choice is up to you.


Acrylic aquariums are very light. They are easier to lift, making acrylic a good choice for large tanks as you should be able to lift them without assistance. They are generally easier to transport and move.

Another big advantage of acrylic is that it is slightly more forgiving than glass. If you have children in your home this is particularly important. They can withstand a minor impact or impact without cracking or breaking.

The bonding process used to make acrylic trays is quite impressive. They probably won’t leak and hold up very well over time. The seams are often so well done that they are practically invisible, making the view of your tank more spectacular.

Temperature is another thing to consider. Acrylic retains heat better than glass, so there will be fewer and fewer extreme temperature fluctuations.


Glass aquariums do not scratch, but they are more susceptible to cracks and breakage. They also hold their shape, whereas an acrylic tank can bend or warp over time.

While acrylic tanks look great at first, they can yellow or cloud over time if exposed to too much sunlight. On the other hand, the glass will never cloud or discolor no matter how long it is in the sun.

Glass is heavy and impractical for large tanks of, say, 200 gallons. It’s too much to lift and can really strain the stand or even the floor.

Another thing to think about is that glass usually only comes in ordinary forms. That said, rectangular tanks are best suited for goldfish, so this is still a suitable option.



Contrary to popular belief, goldfish don’t really thrive in a small bowl. In fact, they need a much larger tank to grow to their fullest potential and live long and healthy lives.

Our top pick for the best goldfish tank is the SeaClear Acrylic Aquarium Combo. It is a beautiful tank that looks perfect and crystal clear, giving you an ideal view of your pet. Plus it is really strong, lightweight and leak proof.

We also like that it is a small set that includes the tank and a lamp. This way you can still take the time to do your research and choose the filter you want to use.
